1. Select the "Measure workpiece zero" function (see steps 1 and 2
above).
2. Press the "Rectangular pocket" softkey.
- OR -
Press the "1 hole" softkey.
- OR -
Press the "2 holes" softkey.
- OR -
Press the "3 holes" softkey.
- OR -
Press the "4 holes" softkey.
- OR -
If these softkeys are not listed, press any vertical softkey (with the
exception of "Set edge") and in the drop-down list, select the desired
measurement version.
3. Traverse the workpiece probe to approximately the center above the
rectangular pocket or the hole or for several, above the first hole to be
measured.
4. Specify whether you want "Measurement only" or in which work offset
you want to store the zero point.
5.
• If you do make any entry in the entry field "L" length (1st geometry
axis of the working plane) or "W" width (2nd geometry axis of the
working plane) of the pocket, then the axis moves with the
measuring feedrate from the starting point.
If the measuring stroke does not reach the edge, then this data must
be approximately entered. However, the measuring sequence is
then also shortened as part of the measuring distance is moved with
rapid traverse.
- OR -
• If you do not make any entry in the entry field "Øhole", then the axis
moves with the measuring feedrate from the starting point.
If the measuring stroke does not reach the edge of the hole, then the
approximate diameter must be entered. However, the measuring
sequence is then also shortened as part of the measuring distance is
moved with rapid traverse.
• Enter an angle in "Probe angle". With the probe angle you can turn
the traversing direction of the probe through any angle.
